#### Example of Calculating Nominals

The Calculate Noms button calculates the X, Y, and Z nominal values from new offsets entered.

For example, suppose you construct an offset plane between three circles (CIR1, CIR2, and CIR3). After selecting the features and clicking the Offsets button, you have X, Y, and Z nominals of:

X = 6

Y = 2

Z = 0.95

If you change the offset values by 3.0 for each circle and click the Calculate Noms button, the X, Y, and Z are updated to:

X = 6

Y = 2

Z = 3.95

If you then click OK and construct the offset line, you'll notice that the newly constructed line lies 3.0 units higher in the Z axis.

Plane offsets only apply the offset in the Z axis.
